Abstract	Available chlorine has been widely used for the sterilization and disinfection of the tap water supply. The development of a device is awaited which will enable the generation of available chlorine at high concentrations with high efficiency. The purpose of this paper is to propose optimum operation conditions for available chlorine production from the standpoint of high concentration. The experiment is conducted using a flow-type reactor with narrow and parallel electrode plates, even though it lacks a barrier membrane between the plates. The governing factors are the electrode plate interval and the flow rate of sodium chloride solution from the viewpoint of hydrodynamics, and the concentration of sodium chloride of the medium and current density supplied to the electrode plates from the standpoint of chemical reactions. The concentration of available chlorine was measured using a residual chlorine meter. The influence of operation conditions on the concentration of available chlorine is shown. Moreover, the governing factors are examined using experimental design because many experimental conditions are expected for the above conditions. As a result, the high concentration production of available chlorine is strongly affected by the current density as well as sodium chloride concentration. These results will be useful for producing chlorinated water, called hypochlorous acid water.
